Facts and features

• Powerful
  • Supports synchronous event dispatching and asynchronous event queue.

  • Doesn't depend on HTML DOM. eventjs works for non-browser environment.
  • Well tested. Backed by unit tests.
• Fast
  • Much faster than HTML DOM event listener system.
  • The EventQueue can process 5M events in 1 second (5K events per millisecond, when there are 100 event in the queue).
  • The CallbackList can invoke 1M callbacks in 1 second (1000 callbacks per millisecond).
